OIL ER.

SPECIFICATION forming part Of Letters Patent NO. 431,829, dated July 8, 1890.

Apnlication filed February 18 1890. Serial No. 340,912. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD A. WEIDMAN, of Geneva, in the county of Ontario, in the State of New York, have invented new and useful Improvements in Oilers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to devices for oiling bearings, especially'those which are oiled automatically, intermittently, and while in motion or at full speed.

My object is to produce an oiler adapted to intermittently supply oil in uniform quantity to a bearing while it is in motion at full speed by dropping the oil into a trough from a stationary holder having holes through the bottom, through which the oil oozes, collecting upon the bottom of the trough in drops,which are brushed off and picked up with every revolution and are conducted to the bearing, all without any spatterin g or throwing of oil, even at the highest speeds.

My invention consists in the several novel features of construction and operation hereinafter described, and which are specifically set forth in the claims hereto annexed.

It is constructed as follows, reference being had to the accompanying drawings, in which Figure 1 is an elevation of a part of the crank-arm of 'a crank-shaft, the crank-pin thereon, the pitman-rod connected to the crank-pin, and the oiler in the position these parts assume when taking oil. Fig. 2 is a vertical section of the tubular wiper mounted on top of the pitman-rod strap. Fig. 3 is an elevation of an oil-trough carrier, in which both ends of the trough are supported by a spring-connection. Fig. 4 is a plan view of the top of the trough-holder. Fig. 5 is a longitudinal section of the trough.

Ais the crank-arm, mounted in any manner upon the crank-shaft 1 and provided with the crank-pin 2.

B is the pitman-rod, connected to the crankpin by the boxes 3 and strap 4, keyed together, as shown. Upon the top of the strap I secure the tubular wiper 5, and which opens downward onto the crank-pin. This wiper is filled with a packing 6, of an elastic and yielding absorbent, consisting of vwicking or its equivalent passed down through the body and neck and tied in a knot 7 below the bottom. This knot prevents the packing from being forced upward into the wiper, thus leaving the free ends of full length and always in' pipe 9, the lower end of whichis threaded externally and having the opening in the point 10 contracted. The lower end passes through the hole 11 in the upper end of the Col 0 shaped spring 12, and 13 is a nut securing the spring in position. Upon the lower end of the spring I form or secure a trough 14, (shown in the drawings as V-shaped or tubular in cross-section,) and it is provided with perforations 15 through the bottom.

The oil-holder is adapted topermitauniform quantity of oilto drop from itinto the pipe 9,and thence into the trough 14, whence it passes through the perforations 15 and gathers in drops upon the bottom of the trough. Then with each revolution of the crank-arm the wiper comes in contact with the bottom of the trough, at first with a simple contact of the ends of the brush with it, then with increasing pressure up to the center, and then with a reducing pressure until it is clear therefrom. The brush in this mode of operation will thus wholly absorb all of the oil upon the bottom of the trough, so that none of it is thrown off from the brush and lost. This oil is then passed down through and along the wicking to and into the free ends,

2. The combination, with the oil-holder and discharge-pipe therefrom and the oil-trough supported beneath the pipe upon the spring, 15 of a wiper concaved transversely. and provided with a packing projecting above its body in the concavity and knotted below its lower end, as set forth.

3. The combination,with the oil-trough, of a wiper concaved transversely and provided 20 with a packing projecting above its body in the concavity and knotted below its lower end, as set forth.

In witness whereof I have hereunto set my hand this 27th day of January, 1890.

RICHARD A. VVEIDMAN.
